WATER- -ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 276,481, dated April24:, 1883.

Application tiled December 6, 1882. (No model.) i

To all whom it may concern Be itknown that 1, WILLIAM M. Scorer, ofLockport, in the the county of Niagara and State of New York, haveinvented certain new and useful Improvements in VVater-Elevators; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which forms part of this specification.

My invention relates to an improvement in draining mines; and itconsists in the combination of two tanks provided with suitablestop-cocks, a supply-pipe which connected with the upper tank, theair-pipe which connects the two tanks together, and a pipe connectedwith the lower tank, through which the water from the mine is forced,allof which will be more fully described hereinafter.

The object of my invention is to utilize a head or fall of water for thepurpose of loreing the water from mines, and thus dispense with the useof pumps and other similar machines.

The accompanying drawing represents a vertical section of an apparatusembodying my invention.

A represents a tank or reservoir of any suit able shape or construction,and which is to be placed at a point in the mine below the level of thewater. At the bottom of this tank is formed a cock, B, and at its top isformed a second one, 0, of smaller diameter. These two cocks B O areunited together by a rod, D, which extends up above the surface of theground, so as to be readily operated. Thesetwo cocks are arranged insuch relation to each other that they both open and close at the sametime. Leading from near the bottom of this tank A is the water-pipe F,through which the water from the mine is forced up above the surface ofthe ground. Also, connected with this tank A, at its top, is theair-pipe G, which is connected at its upperend with a second and largertank, II. This pipe G is made to extend. above the top of the'tauk H, asshown, and is provided with a suitable stopcock, I, which should beair-tight. The tank His also provided with two stopcocks, J L,

similar to those in the smaller tank, A; but these two upper cocks neednot be connected together unless it is so desired. This tank H will beplaced either upon the surface of the ground or at any suitableelevation above it, according to the height of the head of water whichis to be utilized. Leading into this tank II, 'and extending down nearits bottom, is the water-supply pipe 0, which is provided with thestop-cock P, and which pipe is connected with the elevated supply oftvater.

The two stop-cocks J "L are first open, so as to allow the tank H tofill with water, and are then closed". The two stop-cocks B O are alsoopen, so as to allow the lower tank, A, to fill with the water that isdown in the mine, and arethen closed. The stop-cock I in the pipe Grhaving been opened, the stop-cock P is also opened, and the water flowsfrom the source of supply into the tank II-and fills it from the bottomupward. The air that was in this tank H, as rapid-1y as it is displacedby the water, is forced through the pipe G into the tank A, where itexerts its pressure upon the top of the water that is contained in thetank. This pressure of the air will cause the water in the tank to risethrough the'pipe F to the top of the ground- In case there is notsufficient air in the upper tank to displace all of the water in thetank A, the stop-cock I in' the pipe G can be closed, so as to keep theair that has been compressed in the pipe G and the top of the tank Afrom escaping. The stop-cock P in the pipe 0 is first closed, and thenthe two stop-cocks J L in the tank H are opened, so as to allow thewater to escape. The two stopcocks J L are again closed and the twococks I I again opened, and a a second quantity of condensed air isforced down into the tank A, so as to elevate another quantity of water.This process can be carried on very rapidly until nearly all ofthe waterthat was contained in the tank A is forced up above the surface of theground. After the air has been condensed to a certain extent in the topof the tank A, when the stopcock is opened the sudden expansion of theair which has been compressed in the tank A will blow all of the waterthat was left in the upper tank, H, out through the lower stopcock, L,in the form of bail.
